hermes-plugin-clawrouter

ClawRouter for Hermes — 55+ LLMs, x402 USDC micropayments, smart routing.

Wraps the existing ClawRouter TypeScript proxy as a Hermes plugin. Wallet (BIP-39, Base + Solana), routing (15-dimension scorer), and x402 payment all stay in the canonical TS implementation — this is a thin Python adapter.

Install

pip install hermes-plugin-clawrouter
hermes plugins enable clawrouter
hermes clawrouter setup
hermes clawrouter doctor

setup writes the model-provider plugin to ~/.hermes/plugins/model-providers/clawrouter/ (Hermes only loads provider plugins from that directory; PyPI entry points can't ship them).

Usage

In a Hermes chat:

• Set model to blockrun/auto to use ClawRouter's smart routing.
• /clawrouter wallet — address + USDC balance
• /clawrouter stats — proxy usage stats
• /clawrouter status — proxy health
• /clawrouter route <eco|auto|premium> — switch routing profile

Tools (callable from chat):

• clawrouter_image_generate — 55+ models incl. DALL-E 3, Flux, Nano Banana
• clawrouter_video_generate — Seedance, Grok Imagine
• clawrouter_web_search — Exa-powered

Wallet

The plugin reads the canonical wallet at ~/.openclaw/blockrun/mnemonic (24-word BIP-39 phrase, mode 0o600). To create one:

npx @blockrun/clawrouter setup

Then fund USDC on Base or Solana — $5 covers thousands of requests, non-custodial. The plugin never writes to the wallet.

Headless / CI

Set BLOCKRUN_WALLET_KEY=<0x raw EVM hex> to bypass the mnemonic file (EVM-only — Solana derivation unavailable).

Environment variables

Variable	Effect
CLAWROUTER_PROXY_URL	Point at an externally-managed proxy (e.g. https://my-host/v1). Skips local spawn entirely.
HERMES_CLAWROUTER_AUTOSPAWN=0	Disable lazy spawn; require npx @blockrun/clawrouter to be running already.
BLOCKRUN_WALLET_KEY	Raw EVM hex private key — overrides the mnemonic file.
CLAWROUTER_ROUTING_PROFILE	eco / auto / premium. Forwarded to the proxy on spawn.

How it works

1. hermes starts → the entry-point plugin is loaded → register(ctx) wires tools, slash commands, CLI, and the skill.
2. hermes clawrouter setup materializes ~/.hermes/plugins/model-providers/clawrouter/{plugin.yaml,__init__.py} from bundled package data.
3. Hermes' providers/__init__.py discovers the materialized directory and registers the ClawRouterProfile, pointing base_url at http://127.0.0.1:<port>/v1.
4. First tool call or chat turn → the supervisor probes :8402, spawns npx -y @blockrun/clawrouter --port <port> if needed, waits ≤30s for /v1/models, then forwards the request.
5. A heartbeat thread restarts the subprocess on death (max 3 restarts/min).

Distribution

The Python package ships both logical plugins:

• Standalone plugin (this PyPI entry point): tools, slash commands, CLI, skill.
• Model-provider plugin (materialized into ~/.hermes/plugins/model-providers/clawrouter/ by hermes clawrouter setup): ProviderProfile registration.

This split is required because Hermes' PluginManager (hermes_cli/plugins.py) skips register(ctx) for kind: model-provider, and entry-point plugins always load as kind: standalone.
